1 Claim. 1 This "inven-tionrelates to an improved window assembly.

It is illustrated'in -a storm window and screen assembly adapted to be inserted within a window opening adjacent to and outside of the conventional sliding window sash provided 'insuch opening. It might be embodied in a window and screen assembly of the conventional rather then It is illustrated as embodied in an assembly composed largely of metal and preierablyof relatively thin sheet metal of light weight.

-An object is to provide a window assembly designed to accommodate two sliding window sashesand a screen sash in such amanner that the sashes may be quickly removed or installed in 'placeand the screen sash'may'be stored when not in use along-side of the lower window sash.

Another object is to provide such an assembly wherein-the opposed jamb members exhibit adjacent their upper ends a pair of opposed guide channels having an upper sash and exhibiting upper guidechan'nels providing an interval therebetween-through which a sash may be passed out of or into the lower guide channels for removal or insertion of a sash into the window assembly.

7 A further object is to provide awindow assembly wherein the jamb members are provided in their upper halves with a pair of-opposed upper guide channels adapted to'slidably receive'a sash and are provided in their lower halves with a pair of opposed lower'guide channels adapted'to slidably receive a sash and wherein the inner side wallsof the lower guide channels terminate at the top spaced below and offset inwardly the lower ends of t'heinner side walls'of the upper guide channels providing an interval through which a sash may-be passed into or out of the lower guide channels, and wherein the jamb members also exhibit a'second pair of lower'guide channels positioned inwardly or the first mentioned pair and adapted to slidably receive a sash. A window sash maybe positioned in'the upper pair of guide channels. A screen sash may be positioned in the first mentioned pair of lower guide channels. A second window sash'may be positioned within a second pair of lower guide channels. Thesecond window sash may beremoved upwardly from its guide channels. "The screen sash may be removed upwardly from its ,2 guide channels. Upon removal :of the :screen sash the upper window sash may be lowered into the first mentioned pair of lower guide channels and its upper end swung inwardly and it :may then be removed upwardly therefrom. The reverse operations maybe carried out.

The lower window sash may be provided with a flange extending along its top rail adapted to overhang the screen and abut the bottom rail of the upper window sash. The screen maybe removed and the two window sashes used alone withsaid flange sealing the gap that otherwise would result at their'meeting rails.

Other objects, advantages and meritorious features will more fully iappearfrom the following specification, claim, and accompanying drawings, wherein:

Fig. 2 is a vertical sectional view taken on the line'22 of Fig. v1;

Fig. .3 is a fragmentary perspective of one of the jamb members at the meeting rail position of the upper and lower sashes;

Fig. 4 is a horizontal'sectional view taken on the line 44 of Figs. 2 and '3;

Fig. 5 is a horizontal sectional view taken on the line '5-5 of Figs. '2' and 3;

Fig. 6 is a fragmentary perspective irom'the same vantagepoint as that of Fig. 3 showing the upper sash, the lower sash, and the screen in lace;

Fig. '7 is a vertical sectional View through the lower half of the window assembly showing the position of the upper windowwhen lowered for removal upwardly Fig. 8 is a'vertical sectional View through the upper portion of a window assembly-showing the screen elevated for removal therefrom; and

Fig. 9 is a fragmentary perspective taken from a similar position to that of Fig. 6, but showing a modified form of header member for the lower window frame.

In the drawings the window'assembly isillustrated as 'formed largely of sheet metal, but there isa wood'sill portion l fl and wood jamb portions 12. There is a metal sill l4, channel-shaped in 'cross-sectionto seat over the wood sill l0 and provided with an upright ledge It on the inside. A pair of cooperating metal jamb elements I1 and I8 are provided, as shown particularly in Figs. 3,4, 5 and 6. Each of these elements is channel-shaped in cross-section. The element 11 is shown as received directly overthe wood 'jamb member 12. It is provided with a laterally outwardly extending flange 20. The jamb element [8 is channel-shaped in cross-section and received over the wood jamb l2 and over the cooperating ide walls of the metal jamb element IT, as shown particularly in Figs. 4 and 5. This jamb element I8 has a flange 22 which forms the outer side wall of the upper and lower guide channels hereinafter described. The header of the window assembly is not shown as provided with a wood strip but merely a metal shape indicated by the numeral 24. This shape is folded to define an inner flange 26, an outer flange 2B, and an intermediate flange 30. These metal shapes may be formed of aluminum many other suitable sheet metal. The separate parts may be secured together in any suitable fashion to the wood strips by nails or they may be riveted as desired. The flanges 23 and of the header form a header channel for a slidable upper sash received within the jamb members.

The jamb members exhibit upper and lower guide channels now described. The upper guide channel is completed by an angular section 32 which is shown particularly in Fig. 6. It may be secured by nails or the like 34 extending through the jamb elements I7 and I8 and into the wood jamb strip l2. This angular section 32 has a part 35 which forms with the flange 22 of the jamb element 13 the upper guide channel to receive the upper window U. This upper window pane is provided with a metal sash in Fig. 6. The sill portion 36 has one margin turned over as at 38 to provide a better seal with the screen sash. The side rails of this upper pane sash are formed of metal and indicated as 40. The window screen and its sash are indicated by the letter S. No claim is made to the screen sash in this application, but claim will be made thereto in an application to be filed. The lower window is indicated by the letter L. As shown in Figs. 1

through 8, it is provided with a metal frame to which no claim is herein made. The lower guide channels are formed by a metal strip 42, shaped as shown in Figs. 3 and 5, to provide a flange 44 and spaced therefrom a flange 46. The flange 45 forms the inner side wall of the lower channel within which the screen sash is disposed, the outer wall of which is formed by the flange 22. This inner side wall 46 terminates at its upper end spaced below the inner side wall 35 of the upper channel and offset inwardly therefrom, as shown particularly in Fig. 3.

It is apparent, therefore, that the lower channel formed between the flange 22 and the flange 345 has a channel width greater than the width of the upper channel formed between the flange 22 and the flange 35. The width is such that a sash may be passed through the interval or space between the lower end of the side wall 35 and the upper end of the side wall 45. In Fig. '7 the upper window is shown as lowered into the lower channel formed between the flange 22 and the flange 48. It has its upper end tilted inwardly so that it may be lifted out of such lower channel space. In Fig. 8 the screen is shown as lifted out. of the space and upwardly into the header .4 and as having its lower end swung inwardly to be completely removed from the assembly.

When both windows are in use the screen normally occupies the space shown in Fig. 6, within the lower channel formed between the flanges 22 and 45. This is a non-use position for the screen. The lower window may be removed and the screen used alone to seal the opening at the lower end of the window frame. The screen is provided with shiftable pins 50 extending through its side rails which are adapted to be received within provided openings in the jamb members to hold the screen in the lowered position so as to prevent unauthorized tampering on the outside with the window assembly. These pins may be conventional shiftable plunger type pins.

In order to maintain the sash tight within the assembly and to urge them outwardly against the outer channel wall 22, each jamb member is provided with a leaf spring 52 mounted thereon at the interval between the upper and lower guide channels, as shown in Figs. 3 and 4. These spring elements are shaped as illustrated. One is provided for each jamb member. Each spring element has a leaf portion 54 turned over at its inner margin as at 56 which leaf portion is tensioned so as to lie normally, as shown in Fig. l, exerting a pressure on a sash mounted within either guide channel tending to urge said sash outwardly and to hold the sash snugly. This leaf portion 54 extends transversely across the jamb member so as to lie across the bottoms of the guide channels. The action of the spring member is shown particularly in Figs. 3 and 6. It extends sufficiently far into the upper guide channel to exert a pressure on the upper sash. It extends across the portion of the first mentioned lower guide channel so as to exert a pressure upon the screen sash. It extends completely across the end of the second mentioned lower guide channel as shown in Fig. 3.

In Fig. 9 a modified form of construction is illustrated as compared with the construction of the first eight figures or" the drawing. This figure compares with Fig. 6. In Fig. 6 the lower window is shown as provided with a metal frame wherein the header is of the usual kind. In Fig. 9 the header of the lower window L is formed of sheet metal bent into channel form indicated by the numeral 58. This channel shape receives the edge of the glass pane. This channel shape is bent upwardly upon itself as at 62 and then outwardly forming a flange 64 which flange is folded inwardly at its margin as shown. The edge of this flange bears against the fold 33 of the lower frame member 35 of the upper windown U. It extends across the top of the screen as illustrated in Fig. 9.

Also as shown in Fig. 9 the lower window and the screen are of such a height that the flange portion may extend thereacross and contact the fold 38 of the lower frame member of the upper window. In Fig. 6 illustrative of the embodiment of the invention shown in the first eight figures of the drawing, the lower Window and the screen have a greater height than shown in Fig. 9. It is apparent that if the screen were removed, the major portion of the gap between the lower window and the upper window would be closed by the flange 65.

What I claim is:

In a window assembly opposed J'amb members the upper halves of which define opposed upper sash guide channels superposing opposed pairs of inner and outer sash guide channels exhibited by the lower halves of said jamb members, the outer walls of the upper guide channels constituting a continuation of the outer lower guide channel outer walls, said inner lower sash guide channels ofiset inwardly from said lower outer sash guide channels and said upper sash guide channels, the outer walls of said inner lower sash guide channels formed by the inner walls of said outer lower sash guide channels, the inner walls of said lower inner sash guide channels terminating at the top spaced inwardly and below the lower ends of the opposed inner walls of the upper guide channels, the inner walls of the opposed lower outer guide channels terminating at the top spaced below and ofiset inwardly of the lower ends of the opposed inner walls of the upper guide channels providing an interval between the,

inner walls of the upper and lower guide channels through which a sash may be passed into and out of the lower guide channels, sashes slidably mounted within each of the channels, complementary leaf springs mounted on the jamb together.
